On this week's "Master in Business" podcast, Cuban told Barry Ritholtz that managing a Dairy Queen after his comments was probably the best PR stunt he's ever done.

Dairy Queen franchisee Parrish Chapman pitched to Cuban this idea of managing a Dairy Queen for the day. Cuban says there was a line outside clammering at 6:30 in the morning on that day.

And Cuban said it was Chapman who turned the event into what Cuban called a "circus" that benefitted his business and served as positive PR for Cuban.

Since Cuban bought the Dallas Mavericks in 2000, fines levied against him by the NBA have totaled nearly $2 million, according to Sports Illustrated. Each time Cuban is fined by the NBA, he matches that amount with a charitable donation.

Cuban's full discussion with Ritholtz is wide ranging and a must-listen for anybody interested in the billionaire entrepreneur.
